FIELD OF THE INVENTION

The present invention relates to a support frame structure for electronic device, more particularly a structure that possesses the characteristics of multi-axis mechanism and is able to expand the functions of the mechanism.

BACKGROUND OF THE INVENTION

Conventional support frame structure for electronic device is a construction that allows the mounting of flat panel display, PDA, satellite navigation device and other electronic devices, and enables the adjustment of the position or viewing angle of the electronic device by adjusting the orientation of the support frame structure to facilitate operation or viewing by the user. In the case of liquid crystal display LCD monitor, the dawning of digital age, prevalence of Internet, and the advantages of lightweight, thin form, power waving and lack of radiation have turned LCD monitor into the mainstream choice for computer monitor and home television. Generally a stand is needed for the placement of LCD monitor on a desk for support or adjustment of monitor angle.

In recent years, LCD monitor stand and LCD are commonly separately fabricated and then assembled. When a stand-included LCD monitor is placed on a desk, it is also easy to adjust the tilting angles of the LCD.

The recent trend is that LCD monitors marketed by different makers are increasing in size. More and more large-size and heavier LCD monitors are in mass production. When large-size LCD monitor is assembled to the stand, it puts the stand under greater loading. For example, when the LCD monitor stand is in a smaller forward-tilt angle, the stand structure bears less weight load. Conversely when the stand is adjusted to bigger forward-tilt angle, the entire stand structure is subject to greater weight load. Conventional LCD monitor stands are not designed to adapt to varying loading, therefore not having a structure to respond to different weight loads and unable to provide sturdy support when screen size and tilting angle change.

To address the drawbacks of conventional support for electronic devices, the present invention deals with a support frame structure for electronic device.
